Be itrknorwn that I, EARL, W. PETERSON, a

citizen of the United States, residing ati Chicago, in the county of.Cookand State of may be, V,is preferably made in box form from a singlesheet of. metal, so folded that its edges in the final showdown formoutlllinos, have invented a certain new useful Improvement in -MetalADoors, Of which the following is a specification. Y

This invention relates tometal doors for use in lireproof buildings andthe like, and

- its Objectis Vto provide means by rwhichftlie "f constituent parts ofthe door can be assembledwith the minimum amount of work,`

consequent' expense, and specifically with little or no punching,rivetingor welding The invention consists iii-means attainingkv easilyand cheaply made; whichis satisfactoryV in use and is not readily liableto get out of order. 1

:More particularly the invention consists in many features and detailsof construction which will be hereafter more fully set-,forth in thespecification and claims. g

Referring to the drawings in which like numerals designate the sameparts throughout the several views? the foregoing objects; which can Vbevery Figure lis a sidexvie'wofy the door illustrating this invention inkits preferredforrn,` a portion oftherupperr right-hand corner beingshown partially in section.

Figure 2 is -a sectionalplan view onthe .line2-2 of Figure l. f .Y

Figure 3' is a perspectiveview `of certain essentialparts of the doorconstruction show- Figure 4 is an enlarged perspective view takenat theveXtreme upper end of Figure 3. Figure 1 shows a conventionaljtype ofmetal 'doorhaving' two parallel vertical-Stiles 10 and 12 Vconnectedtogether by `any kconvenient number of cross-rails-in the particularcase here illustrated three, 14, 16

and 18. Theconstruction thus vfar described leaves spaces between'thebordering stiles and rails for twopanels 20fand 22 which are identicalexcept as to size.y `The finished door, shown, is rendered attractive inappearance by the presence .of apparently merely decorative moldings24and 26 which occupy the triangular spaces f28and 3Q; formed at thejunctures of the fvarious panels with the bordering Stiles or rails,- asthe case maybe. Y i 1 The problem solved by this invention is to soconstruct the various parts referred to 30V and 32, making 1, SerialNo.585,648.

' that, theyr may befassembled in' themanner i described practicallywithout the use of rivets, solder, bolts or-screws.

1 ln attaining the desired result, each rail or stile, as the casewaidly projecting parallelcontacting flanges Y in effect a compoundflange for the' given stile or rail. Each-of these compound fianges30f32has punched throughit Lt-convenient intervals along its lengthVperforations 34. l

Vlf it is desiredk that the finished door panels 20 and 22 shall beexactly in the middlel f of the thickness of the door as determined bythe thickness of the border u member, stiles or rails, the bordermembers are soV constructed Athat these compound flanges 30-32 will beoff-set toone sidevof the central axis of the ,border member as clearlyshown in Figure 2. :The construction just referred to is not at allessential tothe invention if for any reason'the constructorV is willingthat the panel shall not be central to the ,thickness-of the door.l lnany event,`these compound flanges 30432 should be. soplaced that whenthe border member,xstile or rail is placed around or adjacent to thepanel, the panel vand flange willV occupy approximately the posivtionshown in Figure 2 with just sufficientjspacefbetween them soV as toallow aplate member 24? formed atan acute angle to the rmainportionof'the molding 24 to lie between the flange and panel in such apositionthat rip-standing prongs or teeth 36 0n the edge` of platemember 24ZL canventer the i 'perfoi'ations 34, heretofore referred to,and

n function of positioning the fiange members 30 and 32 with reference toAeach other `and preventing the movement of molding member 24 to theleft', as viewed in Figures 2 and 3, away from the border member (10) ofthe door. The angularity of themember 24a of the molding 24 is suchperform the double vthat when this molding is in place, it, as shown inFigure 2, engages both sides of the compound flange 30k32 and thusvholds the flanges against separating movement one froml the other. Thismolding 24, therefore, in addition to closing triangular space'28between the panel and border member, re-

'tains the, border member itself in closed position without the use ofbolts or rivets between the two flange members 30 and 32 llO and isitself retained inthis covering posimember away from the border member.The parts thus far described are :therefore self,- locking,vprovidedthat means is provided for holding the panel member against the member24; of the molding 24. The mechay nism for this purpose is of'exceedingly simple construction and kincludes merely another moldingmember` 38 on the side of' `panel QOwhichis opposite the molding memberthe same being, before,lof triangular form to close the space betweenthek panel and the border members, it being provided with a flat plate'38 bearing against the panel 2O and a corrugated locking plate 40adaptedtospring under the corresponding corrugated latch plate lsuitablysecured to the adjacent border member, stile or rail by any suitableymeans as, for instancethe rivets 4,4. The result lof theconstructionlast described is that all the operator has to do to firmlylock the panel member against Athe plate 243 of molding member 24 is toslip the member Ll0 of molding lmemberfS under corrugated latch member42 which is of spring material until the locking device operates inobvious manner, whereupon the second molding member-38 is rigidlysecured Ain place and all the other parts referred to areirigidlysecured in place Iand the door rha-sbeenso assembled without any `holepunching except that :for the vperforations and for the rivets all. Theoperator I'has fhad to,in assembling, use no rivets, bolts, screws,solderlor welding.

'Having-thus described my invention, what 'l claim as new and desire-tosecure by Letters Patent 'is '1. Iii-mechanism ofthe class-described, incombination with a panel and a bordering member, a flange projectingfrom 'the bor dering member :parallel to the side Aof the panel and adjacentto its edge, `a 'molding on the same side of panel as and coveringsaid flange, closing'the angular space between the panel and borderingmember, secured in place 4by means kof a molding part which Vpasses in`between the panel and said flanges and enters a recess formed for it insaid `flange and means holding the panel against said molding andflange.

2. ln mechanism of the class described, a box-'lilac border made from asheet of flat material so folded that adjacent side edges projectparallel to each other fto form a double thickness flange in which thereare formed transverse perforations, a panel projecti-ng from the -bordermember parallel to the flange, and amolding member covering said flangeand the angular space between the border'member and panel having a partwhich passes between the flange and panel Y, proj ect parallel to eachother to form a double thickness flange in which there are formedtransverse perforations, a panel projecting from thelfborder memberparallel to the flange, a molding member covering said flange and theangularspace between the border `member and panel having a part whichpasses between the flange and panel and into the perforations in theflange to thereby secure theparts together, andmeans holding the panelagainst said molding and flange. Y

ln mechanism ofthe class described, in combination with a'panel and abordering member, a flange projecting from the bordering member parallel.to the side of the panel and adjacent to its edge, a molding on thesame side of panel as and coveringisaid flange, closing the langularspace between the panel and bordering member, secured in place by meansof a molding part which passes in between the panel and said flanges andenters a recess formed for it in said flange, another molding oppositethe first one yadjacent to the border member and' panel, and spring'snap mechanism for securing the last mentioned :molding in position tohold allthe parts in'place.

5. In mechanism ofthe lclass described, a box-like border vmade from asheet of flat material so folded that adjacent side edges projectparallelto each other to form a double thickness flange in Ywhich thereVare formed transverse perforationaja panel projecting from the `border''member parallelfto ,the flange, l av molding member covering saidflange and the angular space between the border ,member and panel,having a part Ywhich passes between the flange l,and Vpanel and intothe perforations Vin the flange to thereby `secure the parts together,another molding opposite the first one adjacent to the border ymemberand panel, and spring snap mechanism for securing the 'last men- -tioncdmolding in vposition to `holdk all the lparts in place.

6. ln vmechanism of theclass described, a

molding member `having a flat portion for passage between a. panel and aborder-member flange provided with projecting teethto enter openings insuch a flange and acovering portion at an acute angle thereto, adaptedto cover the angular space between such a border member and such apanel.
